Process for preparing an electrophotographic imaging member

Abstract

An electrophotographic imaging member is prepared by applying a charge generating layer to an underlying layer and drying the charge generating layer at ambient temperature.

What is claimed is: 
     
       1. A process for preparing an electrophotographic imaging member having a charge generating layer and a charge transport layer, said process comprising: applying a charge generating layer to an underlying layer and drying said charge generating layer at ambient temperature; and   applying a charge transport layer to said charge generating layer prior to drying said charge transport layer.   
     
     
       2. The process according to claim 1, wherein said charge generator material is dissolved in a solvent. 
     
     
       3. The process according to claim 2, wherein the solvent is selected from the group consisting of monochlorobenzene, tetrahydrofuran, cyclohexanone, methylenechloride, 1,1,1-trichloroethane, 1,1,2trichloroethane, dichloroethyene, dichloroethane, toluene and mixtures thereof. 
     
     
       4. The process according to claim 3, wherein the charge generating material comprises a film forming binder and a photogenerating pigment and the film forming binder, photogenerating pigment and solvent are selected from the group of combinations consisting of polyvinylbutyral, titanyl phthalocyanine and tetrahydrofuran; phenoxy resin, copper phthalocyanine and toluene; and polyester resin, vanadyl phthalocyanine and a mixture of methylene chloride and 1,2-dichloroethane. 
     
     
       5. The process according to claim 1, wherein the charge generating layer is formed by applying said layer by spray coating, dip coating, roll coating, Meyer bar coating, bead coating or curtain flow coating. 
     
     
       6. A photoreceptor made by a process according to claim 1.
